Firefox Marketplace is a discovery and distribution platform for web apps. It imbues Mozilla's principles of transparency, user control, and open innovation that locked-down platforms lack. Its mission is to promote a free and open web.

We announced in March 2016 that the Firefox OS Marketplace will remain open until at least January 2018. We have since made the decision to shut down Firefox Marketplace on March 30th of this year. Thank you so much for your participation in this project. Together we grew Marketplace to touch over 50M unique users, in over 30 countries and 50 languages and explored the boundaries of the web across multiple platforms. Your contributions and expertise have been greatly appreciated! With sincerest thanks, Firefox OS Marketplace Team

Marketplace no longer accepts submissions or updates to apps. Since Firefox OS has been discontinued as a commercial product, Marketplace is no longer receiving very many submissions. Certain events and reallocation of resources to other areas have led us to make a decision to discontinue app submission. The apps in Marketplace can still be downloaded and function on Firefox OS devices. B2G OS, the open source project based on Firefox OS, can install and run non-privileged, non-packaged web apps from any web site.
